To all fac/2,0m t may ccm.'

Be it known that l, Heco Betonm., a citiZen of the United States, residing at Chicago in the county of (look and State of Illinois, have inventedL a certain new and useful Improvement in Cutters, of which the following` a specification,

My invention relates to a belt cutter, and particularly to i hine Lfor cutting small, endless belts Ytrom broad. endlessl belt units. lt has for one purpose to provide a machine which will cut a large number oit smaller belts simultaneously from a large b'ilL nother object is to provide a machine which will cut small belts `of if-shaped cross-section. Another object to provide a machine for cutting fillets. .l provide a ma chine for carryingv out all ci these itunetions, which is adjustable to practically any length of belt and adjustable to any angle ot V-shaped belt, and adjustable for wear, which shall be easy to operate and quick to set and adjust. Other objects will appear from time'to time in the course of the specilication.

I illustrate my invention more or less diagrammatically in the accompanying drawings74 wherein- F ig'. l is a front elevation;

Like part-s are indicated by like characters throughout the drawings and specification.

A. is any suitable base having an upwardly projecting frame -support A1, having the outwardly projecting; bearing stubs A2 A3 in which rotates the drive shaft A4. Se cured to the shaft A* are the pulleys A5 A6, one of which is keyed tothe shaft and the other rotatable thereon7 and thebelt B may be shifted from one to the other by any suitable means, in order to actuate the machine or bring it to rest. The shifter, as

cut by Serial No., $7,170.

shown7 comprises collar C, rotatable on the stub A2 and secured in place by the set screw C1. `Frojecting from it is the arm C2 having` the stub C3, on which is mounted the square bar C4 which is secured in place by the screw C5. The belt-engaging element C6 is movable along the bar C5 and may be liXed in position by the se't screw C7. The shifting mechanism may thus be rotated about the shaft At, depending on the location of the driving pulley ol the belt B.

Projecting in the opposite direction from the frame A1 is the supporting bracket D bolted thereto as at D1. This bracket is slotted. as at D2, and is provided with a worm D3 having a crank DL rotatable in a bearing D5, the outer end of the worm engaging a perforated screw-threaded lug DS which depends from a sliding block D7 adapted to slide backwards and forwards in theslot D2. and which may be set by the set screw DS. Mounted on the block D7 is a species of turret E, which is circular in horizontal cross-section and is calibrated. Aas at El, to permit adjustment of the tool carried thereby. Mounted on this turret is the rotatable element or plate E2, which may be set in position by the set screw E?. in relation to the calibration. It carries a track element E4 and a sliding block E adapted to be moved along the track. This block is perforated .and screw-threaded to admit the vscrew E, which may be rotated by the crank E?.

Mounted in the block cutting tool F which is adjustable therein and may be secured in place. as, for example` by the clamping element F1 and the bolts F2.

Above and to one side ot the bracket D is the bracket G, bolted to the frame as at G1 and slotted as at G2. Above the slot G2 lies a wooden or fibrous strip G10, the purpose of which will appear later. Adjacent the inner end of the slot is the tixed roller G3, rotatable on the bolt G4. Moi/'able along the slot is the carrying block G5, carrying a similar bolt G and roller G7. This carrying block is engaged by the screw GS, which has associated with it the manual crank Gf.

Mounted 0n the shaft A2, and lying adjacent the turret mechanism. is the pulley H. about which passes the belt H1. The upper portion of the trame A1 is slotted and provided with track elements l l1, along is any suitable whichmoves a sliding block l2 on which is mounted the pulley lg. The sliding block is controlled by the vertical screw it, having a manual crank l". Projecting outwardly from the frame [il are similar track ele ments K K1, having the sliding block i@ withV a pulley K3 mounted thereon, said sliding block being controlled by the screw K4 having the square end K5, to which the crank may be secured.

vThe tools used with this device may be widely varied. in Figs. 3 and l l have illustrated a single tool M, having` a. double beveled cutting edge M1. This tool is used for cutting inclined-sided or il-shaped belts. In Fig. 6 l illustrate a gang of similar cutting elements which are used to cutstraightsided belts. ln Figs. 7 and 8 l illustrate a fillet-cutting element N, which comprises the two curved cutting surfaces N1 U2, which scoop out a fillet the cross-section of which is shown at N3.

While I have illustrated working device, it will be understood that many changes might be made in the number, size, shape and relation of parts without departing from the spirit of my invention. l wish, therefore, that my drawings be regarded as to a large extent diagrammatic.

The use and operation of my invention are as follows: Y

I illustrate a positively driven belt-cutting` device in which power from any suitable source Vis transmitted to the endless belt from which the smaller belts are to be cut. This belt is driven by a fixed pulley, it being extended about the fixed pulley and two adjustable pulleys. The sliding blocks which carry the movable pulleys may be moved in or out to compensate for any length of belt, or, if desired, one of them may be cut out altogether. The imite-carrying element is, in the first place, adjustable along the slot D2, to compensate for any width of belt. It is, in the second place, adjustable as to angle, by rotation of the plate or turret. And in the third place it is adjustable aX- ially along the length of the knife, to move the knife to and from the work. Finally, there is an additional adjustment shown at F1 F2, for example, in Fig. 2, to compensate for wear of the knife. VThe knife may be set at any angle, the turret and turret plate being calibrated. Y Y

The belt to be worked on passes across the front of the bracket G, and bein-g stretched between the pulleys H and la shows aflat surface to the knife. rlhe wood or fiber Y element G10 lies opposite the cutting point of accurately to specification. The whole knife assembly, of Course, may be moved back and forth to compensate for the width of the belt, and this adjustment, together with theV adjustment for angle, permits any width or angle of belt tobe cut.

ln cutting Vll-shaped belts, the inner edge of the broad belt blank is first sheared o to show the angle illustrated in Fig. 4; then the cut shown in Fig. l is made, and the belt removed and the finished lil-shaped belt withdrawn from the machine. rlhe belt blank is then reversed and moved'into position opposite rthe knife, which cuts another V. The alternate cutting and reversing results in cuts across the Vbig belt, such as are diagrammatically shown in Fig. 5, and thus there is no wastage except the two'small triangles at the ends of the belt', otherwise the entire belt body is used. During the cutting operation the knife is advanced by rotation of the handle E7 and the cutting edge penetrates the belt, which is moving upwardly at that point. The extreme tip of the sharp edge of the knife goes entirely through the belt and into the fiber or wood.

lf square-sided small belts are desired a large number may be cutv at once by mounting a plurality of knives in tandem and moving the entire gang'forward against vthe belt blank, as shown in Fig. 6.

The machine may also be used to cut fillets, the fillet-cutting tool being shown in Figs. 7 and 8. lt scoops from the blank the fillet shown in cross-section at N3, in Fig. 8, and this then may be bisected to form two fillets, as diagrammatically shown 'i Fig. 9. The fillet belt may then be severed and'used in the desired lengths for fitting in corners or for other purposes for which fillets are used.

' Vlhile the present invention has been described primarily for cutting a large number of small belts from a large belt, it will be obvious that it may also be used to trim single belts down, to substitute inclined edges for straight edges, or straight edges for inclinedV edges, and to trim or cut through thick composite belts.

t will be obvious that thepresent invention provides a machine which has enormous fiexiblity in use; which may -be used with belts of anyV length; which may cut belts of a variety of cross-section, and which is easy and economical to use.

Furthermore, it may be used with belts of leather, or fiber, or of anyV other readily cut material and with the tools used for cutting rubber, it may be used to cut rubber belts or strips, in fact this machine is capable of a multitudinous number of appliinf/enea cat-ions which are not herein set forth in detail. i
